The recognition system uses a image histogram for the lead tip check. So, perhaps you were scanning the area from the lead edge to .1-.2 towards the body of your QFP and not fulfilling the required pixel count for that area; increasing it allowed yo

I've got good news and bad news: GOOD: I love Ag2 solder it's the best, most well behaved, reliable, couldn't ask for a better general purpose solder. BAD: It's leaded. I'd be concerned about embrittlement issues when soldering to gold that was 10 t

Unless your products are rather simple or throughput is not a major concern, you are going to have a hard time finding all of that equipment on that budget without considering used equipment. A low-end pick and place machine will consume that entire

Simple answer is no you cannot do it and why would you?.. is it a cost saving thing? As Dave F correctly points out you have a fair amount of noxious fumes to handle that aren't getting exhausted if you switch of the extraction so they will go to you

Selective Soldering Frames can pull large amounts of heat from the solder wave at the point of contact, effectively lowering the temperature of the solder at the solder joint. You should confirm the temperature of the solder joints by running a therm

I have a supplier that want to upgrade all nails on a huge amount of ICT fixture due to test RoHS compliant PCBAs. My thought is that even if there are a very small fraction of residues left on the pins it will never go over the 1000PPM level. In fu

Looks like you have bad wetting. I will do in this order as it is easier to troubleshoot starting with the machine and transitioning to the PCB: 1. First clean some bare PCBs really good and try again. 2. Check thermal profile 3. Check flux - amount

We are soldering wire 26AWG to jack socket. However after went through washing, baking, coating, curing processes the wire breaks (at joining point with jack socket) during wire dressing. We have tried to increase and decrease the solder amount but r

I have used one (actually 2) of these machines. The upside is you can point to the print-out and tell your customers that you do test for cleanliness, and you pass. The reality of this test is that it tests for exactly 1 type of contamination. The

I think that both pcb prototype manufacturers or factories for big amount, will have their manufacturing capacity, the focus is still depends on your gerber file. You can consult and then place an order. I have used wellpcb, which is focus on rapid
